本期繼續(xù)為同學(xué)們講解托福聽力長難句。
同學(xué)們在學(xué)習(xí)托福聽力的過程中,最頭疼的就是句子的理解,尤其是長難句。但是相對于閱讀文本來說,聽力的問題其實是比較簡答的,我們在理解句子的時候基本只要考劃分句子的主干成分,配合一些短語搭配就可以了,但是關(guān)鍵是要求我們的反應(yīng)速度要非常的快,我們現(xiàn)在就具體以TPO中的句子為例,來分析一下長難句。(TPO2-L4)
Is it the distance of the planets from the Sun? Right. In astronomical units—not perfect, but tantalizingly close.
是從這些行星到太陽的距離嗎?是的用天文單位計算,不算完美但是也很接近了
Um, it isn’t really a scientific law, not in the sense of predicting gravitation mathematically or something, but it’s attempting a pattern in the spacing of the planets, and it was noticed by Bode hundreds of years ago.
這不是一個真正意義上的科學(xué)定律,并不是預(yù)測重力數(shù)值之類,他在嘗試測量星球之間的距離,在幾半年前被Bode發(fā)現(xiàn)。
Well, you can imagine that there was some interest in why the 2.8 spot in the pattern was skipped, and um . . . but there wasn’t anything obvious there, in the early telescopes.
你們可以設(shè)想一下,為什么我們跳過了2.8這個點,在早期的望遠(yuǎn)鏡中我們確實看不見什么東西。
And look, Uranus fits in the next spot in the pattern pretty nicely, um, not perfectly, but close. And so then people got really excited about the validity of this thing and finding the missing object between Mars and Jupiter.
天王星非常符合這個位置,雖然不是非常精準(zhǔn)但是也非常接近了。后來人們對于這個模式的準(zhǔn)確性變得非常感興趣,并且開始尋找火星和木星之間缺失的天體。
And telescopes, remember, were getting better. So people went to work on finding objects that would be at that missing distance from the Sun, and then in 1801, the object Ceres was discovered.
并且天文望遠(yuǎn)鏡也變得越來越好,所以人們開始尋找這里的缺失的天體,后來在1801年谷神星被發(fā)現(xiàn)
And Ceres was in the right place—the missing spot. Uh, but it was way too faint to be a planet. It looked like a little star. Uh, and because of its starlike appearance, um, it was called an “asteroid.”
谷神星正好處于這個位置,但是它太微弱了不可能是一個行星,看上去像一顆小星星,因為它長得很像星星,我們把它叫做小行星。
Ceres was the first and is the largest of what became many objects discovered at that same distance.
谷神星是第一個也是在同一距離發(fā)現(xiàn)的最大的行星。
Not just one thing, but all the objects found at that distance from the asteroid belt. So the asteroid belt is the most famous success of this Bode’s Law. That’s how the asteroid belt was discovered.
在從整個行星帶到這個空檔之間的距離里也算是最大的。行星帶的發(fā)現(xiàn)是波德定律里最成功的發(fā)現(xiàn)。
